Method and apparatus for transmitting/receiving media contents in multimedia system

An apparatus for receiving a media packet in a multimedia system, the apparatus comprising:

• a receiver configured to receive data;
• and
• a processor coupled with the receiver and configured to:
• receive the media packet including data of a unit including at least a part of media data in a payload of the media packet, the unit including at least one media fragment unit (MFU) which is a fragment of the unit, and
• decode the media packet including the data of the unit, the unit being independently decodable in decoding processing,
• wherein the MFU includes a count value indicating a number of at least one subsequent MFU which is dependently decodable based on the MFU in the decoding processing, the at least one subsequent MFU being correlated with the MFU in the decoding processing,
• wherein the MFU includes number information indicating an order of the MFU,
• wherein the MFU includes information indicating a priority of the MFU relative to another MFU within the unit, and
• wherein the payload includes an indicator indicating one of:
• the payload includes one or more complete MFUs,
• the payload includes a first fragment of the MFU,
• the payload includes a last fragment of the MFU, or
• the payload includes a fragment of the MFU that is neither the first fragment nor the last fragment.
